Refactor MN payee logic in preparation for DIP3 (#2215)
* Refactor block payee filling/validation 1. Move out old budget validation into it's own function (IsOldBudgetBlockValueValid) 2. Refactor IsBlockValueValid to bail out early instead of using deep nested if/else blocks. IMHO, I feel that this makes the code much easier to read and less error prone. 3. Refactor/rename CreateSuperblock and CMasternodePayments::FillBlockPayee to be getters without actually modifying the coinbase TX. The coinbase is now only modified from the global FillBlockPayments function. Makes later changes in DIP3 easier (allowing superblock and MN rewards in same block) * Use __func__ for logging in block payee code * Fix code style nit
